Using CW3 and TER on EXT4 now. By the sounds of it, I need to Odin back to DI18 with RFS in order to go to EB13. If that that is the case, then when root is obtained and custom ROM's come out with EXT4 support, can I just simply flash in CW3 since I already converted the file system? I really do not want to go back to RFS and then take all the time to reconfigure my device.
